您好，交换机配制没有问题，看ping交换机丢包嘛

用192.168.2.2ping192.168.2.3，超时

检查下MSR930的拨号口配置

tcp ms 1024

mtu 1492

然后检查下MSR 930的0口是否和交换机的24口连接

和NAT配置

或者在MSR上ping下测试看下外网和内网是否通了

g0口是跟交换机g24连的，现在是不知道路由器上怎么设置了

回复zhiliao_eE4At4:

那现在有2个思路 1.确认下MSR930的外线接在那个扣上的是否和pppoe client绑定的端口一致 2.查看下pppoe拨号是否成功 3.msr930是否配置了NAT 或者说NAT配置是否正确 4.通过在MSR 930ping测试比如ping 223.5.5.5测试公网连通性 ping 192.168.4.1 内网连通性

回复Xcheng:

外网通的，ping内网也能ping通，没有配置NAT

回复zhiliao_eE4At4:

那把NAT配置加上在看看如最简单的吧 [acl a 3000] [ru 100 per ip] [int di 0] [nat out 3000]
